Re: Vox mini 3 amp

In case anyone else asks, there are no schematics available for the Mini 3. I've certainly not seen any.

Re: Vox mini 3 amp

Hi,

Anything is possible of course but I can't advise you where you would need to break into the circuit to do what you want.
Unfortunately I don't have a diagram for the unit but from a visual...

Re: Vox mini 3 amp

Hmm, so it all sounds a bit inconclusive.
I'm still unsure what you are seeing at the headphone socket? Is everything clean there, guitar and Aux? When I test these I use a signal generator so I...

Re: Vox mini 3 amp

On these amps the headphone output is before the chip so if all is well there then it further confirms the fault to be the chip. Not sure I understand when you say the Aux in sounds clean? Do you...

Re: Vox mini 3 amp

No problem, the grounds on these little beasts aren't where you'd expect them!

It does sound like the chip is playing up. Have you tried running it from batteries. In theory it won't make any...

Re: Vox mini 3 amp

Hi Microamp,

I must admit I haven't come across one yet that has been badly distorted. Usually the chip just blows. You could just confirm that the 5V rail is OK that feeds the chip. It's supplied...
